host-rust-bindgen will be required to build several different rust-based
packages, including a Linux kernel with rust modules and mesa3d's
rusticl which is the rust-based implementation of OpenCL.
The Cargo.toml file at the project root is a "virtual manifest". Since
we only want to install rust-bindgen, we can specify RUST_BINDGEN_SUBDIR
= bindgen-cli to use the Cargo.toml from this directory.
